Fish only swimming on one side of the tank

Ever since i removed my wrasse from my tank about, 1 1/2weeks now, all of my fish have been swimming on one side of the tank. That would be my chromis, pair of tomato clows, my cherub angelfish, and my green spotted puffer.

My wrasse was very active and always swimming throughout the entire tank, but since i have taken her out, all of the fish are swimming crammed in one corner of the tank, they wont even venture out in the middle, just stay crammed together on the left side, just floating for the most part.

Any idea what the cause of this is for? When i feed they will go all over the tank, but the rest of the day, the just stay on the left side.

Parameters are ammino,nitrite 0, nitrate 10, Salanity 1.025, ph 8.3

Any idea?

 

let me get this straight, the wrasse left the tank and now they wont venture out. Or you added a wrasse

 

the wrasse left and they wont venture out. she was getting to big for the tank, im not sure if she acted as a dither fish for the rest of the group and now that she's out of the tank, their not as brave??

or if theirs something else going on

 

mine do the same thing

 

I need to give you some karma for knowing what a dither fish is.

As for your problem, I would just leave them alone for a bit. You could have just spooked the poop out of them and need to calm down.

 

That comment came of very sarcastic, there is no need for an attitude here.

and as far as your other statment goes, i hope thats all it is

 

Do you have stray voltage entering that side of the tank?

 

I usually avoid my wife when she starts acting like this. ;D

 

I dont think so, but i guess anything's possible I dont have a device to check for stray voltage though.

 

IDK how a compliment is sarcastic or have attitude, but ok...
